Bannercodes wrong

I have a little problem, I’ve created a banner page with the corresponding codes

For example:<textarea name="comments" cols="60" rows="1" onFocus="this.select()"> <a href="http://beispiel.de"> <img src = "http://beispiel.de/picture/bild.png" alt = "DokuOne" border = "0" /> </ a> </ textarea>

but appear on the website the code like this:

</a><a href="http://beispiel.de"> <img src = "http://beispiel.de/picture/bild.png" border = "0" title = "supports us" old = "doku1 supports us" /> </ a>

How can I change this?

Sorry for my english 🙂
